[0012] 在阅读了此描述之后,对于本领域技术人员而言如何以各种替换实施例和替换应用来实现本发明将是显而易见的。 [0012] After reading this description, those skilled in the art how the various alternative embodiments and alternative applications to implement the invention will be apparent. 然而,虽然本文将对本发明的各种实施例进行了描述,但是理解的是,这些实施例仅通过示例而非限制的方式来呈现。 However, while various embodiments of the present invention will be herein described embodiments, it is understood that these examples are presented by way of limitation by way of example and not limitation. 同样地,对各种替换实施例的此详细描述不应当被理解为限制本发明的范围或宽度。 Similarly, various alternative embodiments of this detailed description of the embodiments should not be construed to limit the scope or breadth of the present invention.

[0013] 图3和4图示了限定目标顶运动传感器系统的第一实施例,其包括一个或多个传感器-目标对。 [0013] FIGS. 3 and 4 illustrate a first embodiment of a top defining a target motion sensor system, comprising one or more sensors - Target. 图3图示了单个限定目标/传感器对30,其包括无源红外(P^)传感器32 和定位在距该P^传感器限定距离处的限定目标34。 Figure 3 illustrates a single defined target / sensor pair 30, which comprises a passive infrared (P ^) is positioned at a distance sensor 32 and the P ^ defined distance sensor 34 at a defined target. 传感器32可以包括任何类型的PIR 传感器,诸如热电传感器。 Sensor 32 may comprise any type of PIR sensor, such as a pyroelectric sensor. 在一个实施例中,图3的目标/传感器对或单元30包括系统的被设置成监视设施的周界的一个段,其中,同样的目标/传感器对被布置在围绕该设施间隔开的间隔处,以便在该设施周围形成完整的“围栏”。 In one embodiment, the target of FIG. 3 / sensor or the unit 30 includes a system is set to the monitoring facility of a section of the perimeter, wherein the same target / sensor at intervals around the facility spaced apart are disposed in the in order to form a complete "fence" around the facility. 可替换地,一个或多个这样的对可以被布置成监视室内区域。 Alternatively, one or more interior areas of such monitoring may be arranged.

[0014] 图3的目标34是空间非一致的目标或发射器,其在该图示的实施例中被垂直地定向,不过在替换实施例中该目标可以是水平的或以其它角度的定向。 Target 34 [0014] FIG. 3 is a spatially non-uniform target or emitter, which is oriented vertically in the illustrated embodiment, but in alternate embodiments the target may be horizontal or at other angles of orientation . 所述目标包括两个具有不同发射率的材料的间隔开的垂直定向的杆36,它们被固定在端架38和40之间,其中整个单元被支撑在垂直支撑柱41的顶部。 The target 36 comprises a vertically oriented rods spaced apart two materials having different emission rates, which are secured between the end frames 38 and 40, in which the entire unit is supported at the top of the vertical support column 41. 端架36也可以是具有不同发射率的材料以形成特征目标信号的一部分。 End frame 36 may be a material having a different emission rates to form part of the feature of the target signal. P^传感器32被合并在传感器单元42中,所述传感器单元42以与目标34的目标杆36相似的高度也被支撑在垂直支撑柱44的顶部。 P ^ sensor 32 is incorporated in the sensor unit 42, similar to the sensor unit 42 and the target 34 is a target rod 36 is also supported at the top height of the vertical support column 44. 由于不同发射率的不同材料的原因,该目标发射出特性非一致图案的顶辐射或特征顶轮廓,其在每次扫描被该传感器检测到,除非在该传感器和目标之间存在介入对象的话。 Due to the different materials of different transmission rates, the target emission characteristics of a top non-uniform radiation pattern characteristics or top profile, which is detected by the sensor at each scan, unless there is intervening object between the sensor and the target words.

[0015] 单元42包括外部壳体,其包含如图4中所图示的用于检测到来的顶信号并且对所述信号进行处理以标识监视区域45内的运动的系统。 [0015] The unit 42 comprises an outer housing including a top signal in FIG. 4, illustrated and for detecting the arrival of the signal processing system to identify motion within the monitored area 45. 如图4中所图示的,传感器单元包括传感器光学系统46、Ρ^传感器设备48、输出信号处理电子装置49、诸如计算机或应用特定集成电路之类的处理器50以及警报输出52。 As illustrated in FIG. 4, the optical sensor unit comprises a sensor system 46, Ρ ^ sensor device 48, the output signal processing electronics 49, such as a computer or application specific integrated circuits, the output processor 50 and an alarm 52. 该处理器在替换实施例中可以定位成远离该传感器单元并且可以经由无线通信接收传感器设备48的信号输出。 In an alternative embodiment, the processor may be located remote from the sensor unit and may receive the sensor signal output apparatus 48 via the wireless communication.

[0016] 在一个实施例中,该系统还包括驱动设备(未示出),其相对于该传感器移动该光学系统以使得该传感器的视场反复地横跨监视体积进行扫描。 [0016] In one embodiment, the system further includes a drive device (not shown), which moves the sensor relative to the optical system such that the sensor field of view is repeatedly scanned across the monitored volumes. 该传感器光学系统可以包括适当的反射镜、透镜以及本领域已知的用于把到来的顶辐射聚焦到MR传感器设备上的其它组件。 The optical sensor system may include appropriate mirrors, lenses and known in the art for the incoming radiation onto the top of the other components of the MR sensor device. 每次扫描监视区域时,所述MR传感器设备生成输出信号,该输出信号被信号处理电子装置49进行滤波、放大和数字化以产生传感器输出信号温度轮廓。 Scanning each monitoring area, the MR sensor device generates an output signal, the output signal of the signal processing electronics 49 is filtered, amplified, and digitized to generate a sensor output signal of the temperature profile. 处理器50接收该信号并且确定是否激活听觉或视觉警报52或者其它输出设备,诸如用于门、听觉或视觉警报、至安全人员的通知等等的激活系统。 The processor 50 receives the signal and determines whether to activate an audible or visual alarm 52 or other output device, such as a door, an audible or visual alarm to notify security personnel of the activation system and the like. 该逻辑可以在与该处理器相关联的计算机可读介质上实现。 The logic may be implemented on a readable medium associated with the processor associated with the computer. 该计算机可读介质可以是逻辑电路、固态计算机存储器、基于盘的储存器、基于磁带的储存器或者其它适当的计算机介质。 The computer readable medium may be a logic circuit, a solid-state computer memory, disk-based storage, a tape based storage, or other appropriate computer medium.

[0017] 传感器单元42从处于人大小或更大的量级的目标34接收顶辐射,这使本发明和图1的现有技术有源射束传感器之间的重要差异显著。 [0017] The sensor unit 42 receives radiation from the top in the order of magnitude of the target person 34 or more, which makes an important difference between the present invention and the prior art sensor of FIG 1 was significantly active beam. 在图3的实施例中,如下面所描述的,传感器32是具有移动监视体积的扫描传感器,但是其在替换实施例中可以是具有静态监视体积的静态或连续传感器。 In the embodiment of FIG. 3, as described below, the sensor 32 is a sensor monitoring the movement scanning volume, but it may be an embodiment of a static volume of static or continuous monitoring sensors in alternative embodiments. 在该传感器的整体视场或扫描体积M内,该目标占据了显著的立体角。 Within the overall field of view or scan volume M of the sensor, the target occupies a significant solid angle. 如图3的实施例中所图示的,当所述目标在形状方面为矩形时,与图1的现有技术系统中的有源射束传感器的窄圆柱体射束形状的监视体积相比,该传感器的监视体积45是棱锥体形状的。 Examples of the embodiment illustrated in FIG. 3, when the monitoring of the target volume is rectangular in shape, with a narrow beam of the active sensor cylinder prior art system of FIG. 1 in the beam shape compared monitoring the volume of the sensor 45 is a pyramid shape. 如下面更详细地论述的,这允许该系统比现有技术系统获得多得多的与传感器/目标状况有关的信息。 As discussed in more detail below, this allows the system to obtain much more information to the sensor / target condition than prior art systems related. 此外,与图2的现有技术MR传感器M形成对比,限定目标系统的检测范围被控制为该目标和该传感器之间的距离d,而图2的MR传感器的检测范围不能被准确控制,而是响应于温度、空气清晰度等等影响移动的人和背景之间“所看到的”温度差异的不同状况而大幅变化。 Further, a prior art MR sensor of FIG. 2 M contrast, defining a target detection range of the system is controlled for the distance d between the object and the sensor, the detection range of the MR sensor of FIG. 2 can not be accurately controlled, and in response to temperature, air clarity different conditions like "see" the temperature difference between the background and the movement of the impact vary greatly.

[0018] 如图3中所图示的,目标34占据了扫描体积M在距PIR传感器距离d处的横截面积55的显著部分(其中d是目标和传感器之间的距离)。 [0018] As illustrated in Figure 3, the target 34 occupies a swept volume distance M in a significant fraction of the cross sectional area at a distance d the PIR sensor 55 (where d is the distance between the target and the sensor). 所述目标与现有技术的不同之处在于,如图1中,传感器或接收器监视由来自小型射束或点光源的辐射横越的体积。 It differs from the prior art in that certain, 1, monitored by a sensor or a receiver or a beam of radiation from a point source of small volume across FIG. 在现有技术有源射束传感器系统中,与要检测的对象相比,该射束或源是小的。 In the prior art active beam sensor system, as compared with the object to be detected, or the beam source is small. 相反,在图3的实施例中,单个目标可以属于与要检测的目标大小相似量级的,例如人大小或更大。 In contrast, in the embodiment of FIG. 3, it may belong to a single target to be detected similar to the target size of the order of, for example, human or larger size. 虽然在图3的实施例中使用了单个目标,但是增强型系统可以具有多个目标。 Although the use of a single target in the embodiment of FIG. 3, but the enhanced system may have multiple targets.

[0019] 此实施例提供了具有移动监视体积(扫描)的MR传感器,其产生整体监视体积54,该整体监视体积M包括通过扫描监视体积在一个时刻或另一时刻所监视的所有体积, 并且它还提供了包括定位在该整体监视体积内的非一致顶发射或温度轮廓的对象(或多个对象)的“目标”,因此根据扫描监视体积的大小及其对比时间与该目标的非一致顶发射轮廓的交叉,该传感器经由其扫描监视体积“看到了”随时间变化的顶发射。 [0019] This provides the volume of MR sensor monitoring a mobile (scanning) of the embodiment, that generates the overall volume of the monitor 54, which monitors the overall volume of the volume of M includes all monitored by scanning at a time or another volume of the monitored time, and it is provided that includes monitoring positioned within the overall volume of the top-emitting or non-uniform temperature profile of an object (or objects) "target", so according to the size and volume of the scanning monitored versus time with the target non-uniform a top emission cross profile, the sensor monitoring via its scanning volume "seen" top emission over time. 虽然垂直目标的使用支持许多一般性应用,但是在替换实施例中可以使用水平目标和以其它角度的目标。 Although certain vertical support many general applications, but the embodiment may be used in other levels of the target and the target angle in alternative embodiments. 如下面所描述的,垂直目标对于用于周界监视的“围栏”类型的应用而言特别有用。 As described below, certain particularly useful for vertical perimeter surveillance for "fence" type application.

[0020] 在扫描传感器的监视体积横跨该目标进行扫查时,如上面所描述的,该传感器“看至Γ随时间变化的顶发射,并且生成与该目标的发射轮廓相对应的“特征”输出温度轮廓。通常,特征传感器输出温度轮廓随着每次扫描保持恒定,或者(由于变化的目标状况的原因) 在数分钟的周期上非常缓慢地改变。图4的处理器50保存目标“特征”传感器输出温度轮廓以作为基准。由处理器50检测到较快的信号改变或者来自该特征传感器输出温度轮廓的变化指示介入对象通过占据该目标与该传感器的整体监视体积的交叉所限定的体积45, 已经阻挡了该传感器的该目标的视野。这导致预定警报输出的激活,所述警报输出诸如听觉或视觉警报或者安全人员的通知。在时间上对应于整体监视体积的非目标占据部分(即, 传感器监视体积M的处于棱锥体形状的目标至 [0020] While monitoring the volume of a scanning sensor for scanning across the target, as described above, the sensor "look to Γ top emission over time, and generates the emission profile of the object corresponding to" feature "output of the temperature profile. typically, the temperature profile as characterized in the sensor output is kept constant for each scan, or (due to changes in target conditions) changes very slowly over a period of a few minutes. the processor 50 of FIG. 4 save target" wherein "temperature profile in the sensor output as the reference detector signal from the processor 50 to change faster or feature from the sensor output change indicates the temperature profile of the intervention by occupying the target object is defined by intersection with the entire volume of the monitoring sensor volume 45, has blocking the vision of the target sensor. this causes a predetermined alarm output is activated, the alarm output audible or visible notification such as an alarm or security personnel at the monitoring time corresponding to the entire volume occupied by the non-target portion (i.e., the target is in the shape of a pyramid sensor to monitor the volume of M 感器体积45之外的部分)的信号不包括目标“特征”的部分,并且因此被传感器忽略。因此,目标至传感器体积45只起到目标和扫描传感器之间的“射束”的作用,允许此传感器通过检测横跨该“射束”的对象(例如,人入侵者)来模仿有源射束传感器的功能。由于它仅检测传感器和目标之间发生的改变,所以此系统有利地提供了受控的检测范围,相比于图2的现有技术的常规HR传感器这是改进。 Than the volume of the sensor portion 45) does not include a signal "signature" of the part of the target, and thus ignored by the sensor. Thus, the target volume of the sensor 45 to act as a "beam" between the target and the scanning sensor, this allows the sensor to mimic the function of the active sensor by the beam across the object to be detected "beam" (e.g., human intruders). Because it only detects changes between the sensor and the object, so this system advantageously provides detecting a controlled range, as compared to conventional prior art sensor of FIG HR 2 this is an improvement.

[0021] 由于图3和4的实施例中的大部分监视体积处于人大小的量级(与图1的现有技术有源射束传感器中的小型圆柱体监视区域相比),所以部分阻挡情形是可能的,在其中传感器输出信号可以被用来估计阻挡对象的大小。 [0021] (small compared to the prior art the active cylinder monitoring area beam sensor of FIG. 1) since most of the monitoring volume and the embodiment of Figure 3 is in the order of 4 human-sized, so that the blocking part scenarios are possible, in which the sensor output signal may be used to estimate the size of the blocking object. 这样的系统可以被设置成使得感兴趣的监视空间体积仅包括目标和传感器之间的“射束”的较宽部分。 Such a system may be arranged such that the volume of space monitored includes only the wider portion of interest "beam" between the target and the sensor. [0022] 图3的目标34可以通过提供经由适合的供电加热或冷却布置进行加热或冷却的杆36或端架38、40的部分而被修改。 Target 34 [0022] FIG. 3 may be modified by providing a frame or the end portion 36 of the rod 38 via heating or cooling power for heating or cooling arrangement. 这可以被用来增加不同的发射率部分之间的发射对比度。 This may be used to increase the contrast between different emitted emissivity portion. 例如,杆36中的一个可以被加热,而另一个为了更大的顶发射对比度被冷却,或者可以沿所述杆提供多个交替加热和冷却的部分。 For example, a rod 36 may be heated, while the other top emission for greater contrast is cooled, or may be provided alternately heating and cooling a plurality of portions along the rod. 这能够提供更加生动的标准或特征目标信号以便在诸如雾、雨或雪之类的不利天气状况下进行更好的识别。 This can provide a more vivid or standard characteristics of the target signal for better recognition in adverse weather conditions such as fog, rain or snow, and the like. 可以使用不同形状和配置的替换目标,诸如多个杆、块等等。 Alternatively the target may be used of different shapes and configurations, such as a plurality of rods, blocks and the like.

[0023] 存在使用图3和4的系统的若干种可能方法,它们全部都可以通过对处理器50的适合编程而被使用。 [0023] Several possible methods exist using the system of FIGS. 3 and 4, all of which can be programmed by the processor 50 is adapted to be used. 在一种方法中,所述处理器通过检测来自特征传感器输出温度轮廓的快速变化来检测来到传感器和目标之间的对象或人员,并且发送“检测”信号。 In one method, the processor to an object or person is detected between the sensor and the target by detecting a rapid change in the sensor output from the temperature profile of the feature, and transmits the "detection" signal. 所述处理器能够通过来自特征传感器输出温度轮廓的连续变化来确认保持在传感器和目标之间的对象或人员的连续存在。 The processor can be confirmed in the continuous presence of an object held or personnel between the sensor and the target characterized by continuous changes in the sensor output from the temperature profile. 所述处理器还可以检测目标本身的变更,其也通过特征传感器输出温度轮廓的改变来指示。 The processor may also detect changing the target itself, which is also the output of the temperature profile change is indicated by the features of the sensor. 在入侵者检测安全系统中,这样的变更可能是由于目标破坏,或者由于试图在传感器及其通常目标之间放置诱骗目标。 Intruder detection security system, such a change may be due to destruction of the target, or by attempting to trick the target is placed between the sensor and its normal target.

[0024] 在对象保护系统中,目标可以被限定为一个(或多个)保护对象。 [0024] protection system in a subject, the target can be defined as one (or more) protected. 在检测到可能由于丢失对象而引起的目标轮廓改变时,该处理器就能够发送“检测”或警报信号,其可以指示未授权个体在监视区域中的移动或者受保护对象的移除。 Upon detecting the target profile may be due to changes caused by the loss of objects, the processor can transmit the "detection" or an alarm signal, which may indicate movement or removal of an individual in the surveillance area protected from unauthorized objects. 在另一实施例中,可以把该传感器设置成将整个房间(或者房间中在内部具有一个或多个离散“子目标”的部分)限定为其整体目标。 In another embodiment, the sensor can be arranged to (a part or a room having a plurality of discrete or "sub-target" inside) for the whole room defined overall objective. 在此情况下,该房间不必具有精确设计的发射变化特性,但是该传感器可以被设计为扫查整个房间并且该处理器被编程为获得和存储表示该房间的顶发射轮廓的特征传感器输出信号或温度轮廓。 In this case, the change in emission characteristics of the room does not necessarily have the exact design, but the sensor may be designed to scan the room, and the processor is programmed to obtain and store sensor output signals representing the feature of the top emission profile or room temperature profile. 通过每次扫描,此特征轮廓被“看到”,除非人员正在正常扫描的背景前面移动。 With each scan, the feature contour is "seen", unless the front of the background art are normal scan movement. 根据使用模式,该房间的特征扫描传感器输出温度轮廓的改变可以指示入侵者、破坏、对象窃贼等等,并且在这些情形中的任一情形下激活警报。 The mode of use, wherein the scanning sensor output to change the temperature profile of the room can indicate an intruder, damage, theft, etc. the object, and to activate an alarm either case in those situations. 该传感器还能够检测针对其自身的变更。 The sensor is able to detect changes for itself. 例如,如果通过覆盖或通过喷涂以顶不透明材料而被破坏,则该传感器就不再接收来自该目标的任何顶输入(或者接收到相当大地减少的顶输入)并且没有信号输出,在这种情况下,该处理器能够发送“破坏”或警报信号。 For example, if applied by spraying or by coating a top opaque material is broken, the sensor will no longer receive any input from the top of the target (or received considerably reduced top input) and no signal is output, in this case, next, the processor can send "broken" or an alarm signal. 可以针对长期平均轮廓或“特征”轮廓来检查每个扫描传感器输出温度轮廓以便检测轮廓的快速改变。 Each scan can check the temperature profile of the sensor output for a long-term average profile or "characterized by" profile in order to detect rapid changes in the profile.

[0025] 在一个实施例中,如图5中所图示的,提供了类似围栏的周界监视段60。 [0025] In one embodiment, illustrated in Figure 5, there is provided a surveillance perimeter section 60 similar to the fence. 图5的传感器系统包括第一和第二交互传感器目标对或单元62、64,一个位于两个端点中的每一个处,其中,一组朝向每个方向,以便实现一致的“围栏高度”。 FIG sensor system 5 includes a first and a second interaction of the target or the sensor unit 62, 64, one at each of two endpoints, wherein each group is moved toward a direction so as to achieve consistent "fence height." 每个传感器/目标对被支撑在适当围栏高度的垂直支撑柱65上。 Each sensor / target pair is supported on a suitable vertical support height of the fence post 65. 第一传感器/目标组62具有在下端处的传感器单元32A 和从该传感器单元向上延伸的矩形目标34B。 A first sensor / target group having a sensor unit 62 at the lower end 32A and 34B extending upwardly rectangular target from the sensor unit. 第二交互传感器/目标组64具有从柱65向上延伸的目标34A和在上端处的传感器单元32B。 Second interaction sensor / target having a target group 64 extending upwardly from the column 34A and the sensor unit 65 at the upper end 32B. 传感器单元32A被定位成从传感器/目标组64的目标34A接收辐射并监视体积45A,而传感器单元32B被定位成从传感器/目标组62的目标34B接收辐射并监视体积45B。 The sensor unit 32A is positioned to receive radiation from the target sensor 34A / 64 and the target group monitored volumes 45A, 32B and the sensor unit is positioned to receive radiation from the target 34B sensors / monitors the target set 62 and the volume 45B. 可以在要监视的整个周界周围提供类似的传感器/目标组,这形成了虚拟“围栏”70,其中传感器/目标对或单元62、64的高度等于期望围栏高度。 It may be provided around the entire perimeter of the similar sensor to monitor / target group, which forms a virtual "fence" 70, wherein the height of the sensor / target pair 62, 64 is equal to the desired cells or the height of the fence. 此实施例的一个优势是由于飞行在传感器和目标之间的鸟而引起的信号改变的时间是相对容易确定的。 One advantage of this embodiment is that since the time of flight of the signal change between the sensor and the birds caused by the target is relatively easy to determine. 在图3的信号传感器系统中,目标具有人大小量级的最低大小。 In the signal of the sensor system of Figure 3, the size of the target person with the lowest order of magnitude. 然而, 接近于该传感器飞行的鸟仍然会彻底阻挡该传感器。 However, close to the sensor flying birds still completely block the sensor. 在图5的交互系统中,如果接近于该传感器飞行,鸟潜在地会彻底阻挡传感器之一,但是不会在其它方向上引起任何信号改变。 In the interactive system of FIG. 5, if the sensor is close to flight, the birds will be completely blocked potentially one of the sensors, but the signal does not cause any changes in the other direction. 因此,在此实施例中,人入侵将会通过两个输出信号轮廓的改变而被确认,而由一个传感器/目标对而不是另一对发射的信号的改变会通过信号大小进行进一步分析并且可以被解释为入侵或者被解释为由于被小鸟等阻挡而引起的非紧急情况。 Thus, in this embodiment, the invasion would be confirmed two output signals by changing the profile of a change by the sensor / target pair, rather than the other signals transmitted on the signal can be further analyzed by size and may It is interpreted as the invasion or to be construed as non-emergency situations due to the blocking caused by birds and the like.

[0026] 从传感器端点到目标提供恒定的“围栏高度”的另一方法是在一个端点处放置多个传感器以监视在另一端点处的目标。 [0026] provide a constant from the sensor to the target endpoint another method "fence height" is placed at one end a plurality of sensors to monitor the target at the other endpoint. 所述传感器沿与目标平行并且与目标一样长的(典型地垂直的)线进行放置。 Direction parallel to the sensor and a target as long as the target (typically vertical) line placement. 因此,传感器端处的“围栏高度”由若干垂直放置的传感器来所提供,并且在目标端由该目标限定的监视体积高度来提供。 Therefore, the "fence height" a plurality of vertically disposed at the end of the sensor to provide a sensor, the target and the target end by monitoring the volume defined height is provided.

[0027] 不同于图1的现有技术有源射束传感器,在图3至5的系统中不存在脉冲顶光发射器。 Active sensor beam prior art [0027] Unlike FIG. 1, the absence of a top pulse light emitter in the system of Figures 3 to 5. 这样,由于接收器从不同于其预期配对的传送器接收光(被称作“串扰”的状况)的原因(如针对不同周界部分而安装的)多个系统不互相影响。 The reason for this, since the receiver from the transmitter is different from its counterpart of the intended receiving light (referred to as "cross-talk" situation) (e.g., for different portions of the perimeter of the mounted) a plurality of system does not affect each other. 因此,在不存在串扰的情况下,可以布置相对复杂的“围栏”阵列,图6图示了限定目标顶运动传感器系统65的一种可能实施例,其中把交互传感器-目标对62、64阵列定位成形成虚拟“围栏” 70,其通常由每个传感器目标对之间的带箭头线来指示。 Thus, in the absence of crosstalk may be arranged relatively complex "fence" array, FIG. 6 illustrates a top defining one target motion sensor system 65 in a possible embodiment, in which the interaction sensor - target pair arrays 62 positioned to form a virtual "fence" 70, which is generally indicated by the arrowed lines between each sensor target pair. 如图6的右手侧中所指示的,该布置可以包括布置成以通常X形状形成地交叉的围栏,以便检测封闭区域内的运动。 The right-hand side in FIG. 6 as indicated, the arrangement may comprise a generally arranged in an X-shape are formed intersecting fence, in order to detect motion within the closed area.

[0028] 在图3的实施例中,传感器是扫描传感器,其根据扫描监视体积M的大小以及扫描体积与目标的非一致顶发射轮廓的交叉来检测随时间变化的顶发射。 [0028] In the embodiment of FIG. 3, the sensor is a scanning sensor, which emits a non-uniform cross-profile according to the size of the top scan monitor M and the volume to the target volume scanning to detect time varying top emission. 在替换实施例中, 图3的扫描传感器可以用具有静态监视体积(其可以与图3的体积M相同或者是对应于图3的监视体积45的体积)的连续传感器来替代,并且该限定目标可以代之以具有随时间变化的非一致顶发射轮廓。 In an alternative embodiment, FIG scanning sensor 3 may be a static monitored volumes replaced (which may be the same volume of M in FIG. 3 or corresponding to Figure 3 of the monitoring volume volume 45) of a continuous sensor, and which defines the target It may instead have non-uniform time varying a top emission profile. 在此实施例中,由于目标提供了被放置成远离该传感器但仍在该传感器的固定监视体积内的振荡顶辐射源,所以不需要进行扫描。 In this embodiment, since the goal of providing the sensor is placed away from the top, but still an oscillation monitoring radiation source fixed within the sensor volume, there is no need to scan. 该远程目标单元的辐射促使该传感器产生与其时间变化相对应的特征信号(例如,以振荡频率)。 Wherein the remote target signal radiation generated by the sensor unit causes its corresponding time (e.g., oscillation frequency). 在此实施例中,处理器50针对与与该目标源的时间变化相对应的简单稳定特征信号的特征信号内容偏差而对信号输出进行监视。 Wherein the content of simple and stable signal characteristics of the signal, the processor 50 for a time corresponding to the target and source in this embodiment monitors the deviation signal output. 这样的信号偏差指示介入对象通过占据该目标与该传感器的整体监视体积的交叉所限定的体积,已经阻挡了该传感器的该目标的视野。 Such a signal indicative of a deviation of the target by occupying the interventional object monitoring overall volume of the sensor cross-defined volume of the target has been blocking the vision sensor.

[0029] 如同之前的实施例一样,该目标比点源或小直径射束大,并且可以是人大小的或更大,这基于传感器和目标之间的距离提供了大的监视体积和受控的检测范围。 [0029] As with the previous embodiments, as the target than the large or small diameter beam point source, and may be human or larger size, which provides a large volume of monitoring and controlled distance between the sensor and the target based on detection range. 非一致的振荡辐射目标可以与图3的目标类似,并且可以具有一个或多个变化的发射器,诸如可被受控地加热以具有预定的随时间振荡的温度图案的一个或多个杆36。 Non-uniform oscillatory radiation may be similar to the target and the target of FIG. 3, and may have one or more variations of a transmitter, such as a controlled manner can be heated to a predetermined time having a temperature oscillation pattern or plurality of rods 36 . 可替换地,如图7中示意性图示的,该目标可以是处于恒定温度的杆80,如图7中示意性地图示的,其顶发射被传感器-目标轴线84内的不同温度的遮光板82交替地阻挡和不阻挡或者被“切”。 Alternatively, as schematically illustrated in 7, the target may be a constant temperature in the bars 80, as shown schematically illustrated, which is a top emission sensor - a light-shielding different temperatures within the target axis 84 alternately blocking plate 82 and not be blocked or "cut." 遮光板82通过任何适合的旋转或线性驱动机制在图7的实线位置和虚线位置之间来回移动。 The visor 82 by any suitable drive mechanism for rotary or linear movement back and forth between the solid line position and broken line position of FIG. 在一个实施例中,顶发射在遮光板处于实线位置时被完全阻挡,而在其它实施例中它被部分阻挡。 In one embodiment, a top emission light-shielding plate is completely blocked when the solid line position, while in other embodiments it is partially blocked. 在每种情况下,预定振荡顶辐射发射被该传感器单元看到并且可以被控制器在寻找指示发射路径中的变化时用作特征传感器输出温度轮廓。 In each case, radiation emission is predetermined oscillation top of the sensor unit and can be seen when looking at the controller indicates a change in the transmission path is used as a sensor output characteristic temperature profile.

[0030] 由于“射束”型传感器通常监视长且窄的体积,因此相应地设计其光学系统和检测器。 [0030] As the "beam" type sensors typically long and narrow surveillance volume, thus correspondingly designed optical system and the detector. 有限尺寸的检测器(即,不是“点”检测器)在与聚焦光学系统组合时,产生具有限定视场角度的非平行边缘的视场。 Finite size detector (i.e., not "point" detector) and the focusing optical system at the time of composition, having a field of view to generate a non-parallel edges defining a field of view angles. 由于该角度,视场的横截面积随着距该传感器的距离增加而连续地扩展,并且可以变得比要监视的实际空间的面积宽(诸如走廊或者建筑物周围的周界条带之上的体积)。 Due to this angle, the field of view of cross-sectional area with increasing distance from the sensor is continuously extended, and may become wider than the actual area of ​​the space to be monitored on the perimeter strip around (or building such as corridors volume of). 例如,一应用可能在距该传感器200m距离处要求1米宽的视场,这要求0. 3度的视场。 For example, an application may require a wide field of view at a distance of 200m from the sensor, which requires a field of view 0.3 °. 由于视场角度取决于检测器大小和光学系统焦距之间的比率,并且由于市场上的检测器典型地为至少1.0mm宽,所以使用200mm焦距来提供期望的视场。 Since the field of view angle depends on the ratio between the size of the detector and the optical system focal length, and on the market since the detector typically at least 1.0mm wide, 200mm focal length used to provide the desired field of view. 这样的窄射束MR传感器典型地被容纳在长纵横比的圆柱体或矩形棱柱中,并且利用其长轴在与要监视的体积的长轴相同的方向上进行定向,其通常是水平的。 Such a narrow beam of the MR sensor is typically housed in a cylindrical or rectangular prism longer aspect ratio, and with its long axis oriented in the long axis of the volume to be monitored in the same direction, which is generally horizontal. 然而,有时,包含用于监视窄体积的长焦距光学系统的长的水平定向的传感器单元可能是不期望的。 Sometimes, however, it comprises a horizontally long focal length optical system for monitoring a volume of a narrow orientation sensor unit may not be desirable. 例如,在住宅周围,水平定向的传感器可能类似高度安全的相机,并且因此产生比住宅的住户可能期望的更多的“安全安装”外貌。 For example, around the house, the sensor may be similar to a horizontally oriented high-security camera, and thus produce more than may be desirable residential households more "secure installation" appearance. 图8图示了具有垂直定向的光学系统的P^传感器120的实施例,其可以在上面所描述的任何红外运动传感器系统中或者诸如图1或图2的那些之类的已知PIR 传感器系统中被用作该P^传感器或这些P^传感器之一,其中期望的是传感器具有比其光学系统针对窄视场的所需焦距小的水平尺寸。 FIG 8 illustrates an embodiment having a vertically oriented sensor P ^ of the optical system 120, any system may be an infrared motion sensor as described above or as known in the PIR sensor system of FIG. 1 or FIG. 2 such that one is used as a sensor or sensors that P ^ P ^ those wherein it is desirable for a sensor having a narrow field of view a desired focal length smaller than the horizontal dimension of the optical system.

[0031] 图8的垂直定向的MR传感器设备120具有柱状的、通常为圆柱体的外部壳体83, 其具有在该壳体内部朝着其下端支撑且向上朝向的P^传感器85和基座支撑84。 Vertically oriented MR sensor device [0031] 120 of FIG. 8 has a cylindrical, outer housing 83 is generally cylindrical, having a housing in the inner support towards its lower end and upward toward the sensor 85 and the base P ^ support 84. 在该壳体前面提供了顶窗口或开口86,并且诸如反射镜88之类的光学设备在该壳体中以一角度朝向所述开口进行定位,用于通过某角度(例如,如图8中所图示,大约90度)对该传感器的视场89进行重定向,以提供水平轴线监视体积和长焦距的垂直轴线光学系统之间的接口。 In the front of the housing providing a window or a top opening 86, and an optical device such as a mirror or the like 88 in the housing at an angle towards the opening positioned for by an angle (e.g., FIG. 8 as illustrated, approximately 90 degrees) to redirect the field of view of the sensor 89 to provide an interface between a horizontal axis perpendicular to the optical axis and a system to monitor the volume of a long focal length. 继续考虑上面所提到的住宅示例,这允许窄视场MR传感器的设计,其没有水平定向的特征。 Residential continue to consider the example mentioned above, which allows the design of the narrow field of the MR sensor, which is not horizontally oriented features. 光学元件88提供了垂直至水平(传感器光学系统至监视体积)的接口。 The optical element 88 is provided perpendicular to the horizontal (the optical sensors to the monitoring system volume) interface. 在上面结合图3至7所描述的任何运动传感器系统中,一个或多个MR传感器设备120可以与一个或多个空间或时间非一致的目标一起使用。 Any motion sensor in the above system described in conjunction with FIG. 3-7, the 120 may be associated with one or more spaces or a plurality of MR sensors or devices for use with non-uniform time target. 多个垂直柱120可以在住宅周围布置而不对该住宅产生高度安全安装“外貌”。 A plurality of vertical posts 120 may be disposed around the house without causing the installation height safety "appearance" of the house.

[0032] 上面结合图3至8的实施例所描述的传感器/目标对的P^传感器单元也可以被修改为包括一个或多个附加类型的传感器或入侵检测器,以用于对已经引起P^运动检测的移动对象的类型提供更详细的确认。 Sensor [0032] The above embodiment in conjunction with FIGS. 3 to 8 described / P ^ certain sensor unit pair may also be modified to include one or more additional types of sensors or intrusion detector, which has been caused for P ^ type of moving object motion detection to provide more detailed confirmation. 图9A和9B图示了多个传感器单元90的一个实施例,其包括MR传感器92和相关联的光学元件93、可以是微波天线或多普勒(Doppler)单元的微波单元94以及相机95,所有这些都封闭在具有前壁97的适合外部壳体96中,所述前壁97具有与相机和P^传感器光学系统对准的窗口开口。 9A and 9B illustrate a plurality of sensor units 90 of the embodiment, which includes an MR sensor 92 and the associated optical element 93, the microwave unit may be a microwave antenna or Doppler (Doppler) unit 94 and a camera 95, all of which are enclosed in a suitable outer housing 96 having a front wall 97, a front wall 97 having a window with the camera system and an optical sensor P ^ aligned openings. 如图9A中所图示,遮阳板98 可以被安装在机壳或壳体96上方并且从前壁97向前延伸,其中该单元90意图用于户外使用。 As illustrated in FIG. 9A, the visor 98 may be mounted above the casing or housing 96 and extending forwardly from the front wall 97, wherein the unit 90 is intended for outdoor use. 该MR传感器可以是具有扫描元件99的扫描传感器,并且适合的顶控制电子装置100 和主电子装置或控制器电路102可以安装在壳体96内部。 The MR sensor may be a scanning element having a scanning sensor 99, and control electronics for the top 100 and the main electronic device or control circuit 102 may be mounted within the housing 96.

[0033] 有时,甚至是非常高质量的P^传感器也能够指示该应用不需要的运动种类。 [0033] Sometimes, even a very high quality P ^ sensors can also indicate that the application does not require the type of sport. 例如,P^周界传感器可能指示由于飞行通过其监视体积的鸟的运动。 For example, P ^ Indicates that the perimeter of the sensor may monitor the volume through which the flying bird movement. 为了提供对人而不是小动物或鸟类运动的更好的检测,图9A和9B的单元90将限定目标P^传感器与微波感测单元和相机进行组合,并且可以代替在图3至8的仅MR传感器单元中的任何而被使用。 In order to provide better detection of the person is not moving animals or birds, 9A and 9B, FIG 90 will define the target unit P ^ combined with the microwave sensor sensing unit and a camera, and may be substituted in FIGS. 3 to 8 MR is used only any sensor unit. 在替换实施例中,该单元90可以将P^传感器与一个附加感测单元进行组合,例如仅与微波单元或仅与相机。 In an alternative embodiment, the unit 90 may be P ^ one additional sensor sensing units are combined, for example, only the microwave unit or only the camera. 微波感测单元可以包括微波多普勒收发器、正交多普勒收发器(用于运动方向检测)、调频连续波(Frequency Modulated Continuous Wave, FMCW)收发器(用于运动范围检测),或者超宽带RADAR (也用于运动范围检测),或者其它类型的微波检测器单元。 Microwave sensing unit may include a microwave Doppler transceiver, the quadrature Doppler transceiver (for detecting the direction of movement), FMCW (Frequency Modulated Continuous Wave, FMCW) a transceiver (for detecting motion range), or ultrawideband the RADAR (also for the detection range of motion), or other types of microwave detection unit. 为了改进“飞鸟”的不必要运动指示的情形,可以由处理器结合微波和MR信号大小对微波运动范围信息进行解释,以便确定穿过该周界的移动对象是否太小以至于不是人入侵者。 In order to improve the situation "birds" unwanted movement indicated by the movement of the microwave range information can be explained in conjunction with a microwave and MR signal magnitude by a processor, to determine if a moving object passes through the perimeter intruders who are not too small . 如果所检测的移动对象被检测为非人,则不指示运动并且不生成警报。 If the moving object is detected by detecting a non-human, the motion is not indicated and does not generate an alarm.

[0034] 该相机可以是以IR、NIR和可见光波长的静止或视频相机,并且包括能够对移动对象的特性进行评估的图像处理软件。 [0034] The camera may be in the IR, NIR and visible wavelengths still or video camera, and includes image processing software capable of evaluating the characteristics of the moving object. 再次返回到消除“飞鸟”的不必要运动指示的任务, 这可以通过MR传感器首先检测运动,跟随有由固件结合MR信号特性对相机图像进行加权的过程(例如,关于对象形状)来完成。 Returning again to the task of eliminating "birds" indicative of unwanted movement, which can be moved by the MR sensor is detected first, followed by the process of the camera-weighted MR image signal by firmware binding characteristics (e.g., on the shape of the object) to complete. 可替换地,可以发送最初的MR运动指示,并且由远程人操作员进一步对相机图像进行评估以确定它是否为错误警报。 Alternatively, you can send the original MR movement instructions, and further evaluated by a remote camera image people operator to determine whether it was a false alarm. 在任一种情况下,结果都是不将鸟作为任何进一步动作的指示器。 In either case, the result is not to birds as an indicator of any further action. 为了满足要求最为严格的应用,如图9A和9B 中所图示的,限定目标MR传感器与微波系统和相机这二者进行组合。 In order to meet the most demanding applications, 9A and 9B as illustrated, defining both the target MR sensor and microwave systems and camera combination. 在此情况下,由于微波范围信息、P^信号特性和相机图像大小都可以被组合以产生与移动对象的大小和其它特性有关的确定性信息,所以“飞鸟”的不必要运动指示甚至可以更为容易地被防止。 In this case, since the microwave range information, P ^ signal characteristics, and a camera image size may be combined to produce deterministic information relating to the size and other characteristics of moving objects, so the "birds" indicative of unwanted movement or even more It is easily prevented.

[0035] 图10图示了更适合于室内使用的组合的MR传感器、微波传感器和相机单元110。 [0035] FIG. 10 illustrates a more suitable for indoor use in the compositions of the MR sensor, microwave sensor 110 and the camera unit. 该单元具有外部壳体或机壳112,其具有拱形前壁113,前壁113具有与该壳体内部的迷你PCB (印刷电路板)相机115对准的相机窗口114,以及与顶扫描单元117对准的顶窗口116,所述扫描单元117包括该壳体内部的MR传感器。 The unit has an outer housing or shell 112, which has an arcuate front wall 113, front wall 113 has a mini-PCB and the inner housing (printed circuit board) alignment camera 115 camera window 114, a scanning unit and a top 117 aligned top window 116, the scanning unit 117 includes the inner housing of the MR sensor. 微波多普勒单元118也可以安装在该壳体内部。 Microwave Doppler unit 118 may also be mounted inside the housing. 每个传感器单元被适合地链接到控制器,所述控制器用于监视和处理各种传感器输出以标识移动对象的入侵,以及该对象的大小和其它特性以便排除非人入侵。 Each sensor unit is suitably linked to a controller for monitoring and processing a variety of sensor outputs to identify the moving object intrusion, and the size and other characteristics of the non-human subject so as to exclude invasion.
